On base of detailed analysis of the decomposed coefficients of BOR multiwavelet
the "layer" concept of an image in MWD (multiwavelet domain) was proposed.For this unique character
data can be hidden in different layer subimages
the selection of hiding layer undoubtedly gives another secret key.An adaptive blind watermarking algorithm is put forward to embed a binary image into the first layer subimage and four layers respectively according to above trait.Experimental results show that the two given methods have good imperceptibility and high robustness.
